Lab grown models of embryos, made from clusters of stem cells, are getting increasingly complex. Ethicists, regulators and ...

In her new book "The Stronger Sex," science journalist Starre Vartan dispels myths and misconceptions about the female body.

(RNS) — Scientists have created a human embryo without the use of sperm or an egg — a true test-tube baby. Such embryos cannot (yet) develop into full-grown human beings.

The little clump of cells looked almost like a human embryo. Created from stem cells, without eggs, sperm, or a womb, the embryo model had a yolk sac and a proto-placenta, resembling a state that real ...

Health Living human embryo model conceived without sperm or egg: breakthrough study By Marc Lallanilla Published Sep. 6, 2023, 2:41 p.m. ET ...

When added to lab-grown early reproductive cells, they developed further than previous attempts, forming precursors to human sperm and eggs inside a dish. The cells had a similar genetic and ...

“Our human model is the first … human embryo model that specifies amnion and germ cells, precursor cells of egg and sperm,” California Institute of Technology professor Magdalena Zernicka ...

The goal of IVG is to make unlimited supplies of what Hayashi calls "artificial" eggs and sperm from any cell in the human body. That could let anyone — older, infertile, single, gay, trans ...

The first mice to be created from two fathers, a phenomenon known as androgenesis, have now produced healthy offspring for the first time. Researchers implanted two sperm in an egg with its nucleus ...

Researchers are inching closer to creating human eggs and sperm in the lab that carry a full complement of anyone's DNA. It could revolutionize fertility treatment and raises huge ethical questions.
